The equation $x = y$ represents a line in the coordinate plane. To graph it, note that for every point on the line, the $x$-coordinate is equal to the $y$-coordinate. This means that the points on the line will satisfy this relationship, such as:

• (0, 0)
• (1, 1)
• (2, 2)
• (-1, -1)
• (-2, -2)

This is a straight line that passes through the origin and has a slope of 1 (since the change in $x$ equals the change in $y$).

I can also plot this for you! Would you like me to generate the graph for you?
